Readmissions After Traumatic Brain Injury in the Nationwide Readmissions Database.

INTRODUCTION: Readmissions after a traumatic brain injury (TBI) can have severe impacts on long-term health outcomes as well as rehabilitation. The aim of this descriptive study was to analyze the Nationwide Readmissions Database to determine possible risk factors associated with readmission for patients who previously sustained a TBI. METHODS: This retrospective study used data from the Nationwide Readmissions Database to explore gender, age, injury severity score, comorbidities, index admission hospital size, discharge disposition of the patient, and cause for readmission for adults admitted with a TBI. Multivariable logistic regression was used to assess likelihood of readmission. RESULTS: There was a readmission rate of 28.7% (n = 31,757) among the study population. The primary cause of readmission was either subsequent injury or sequelae of the original injury (n = 8825; 29%) followed by circulatory (n = 5894; 19%) and nervous system issues (n = 2904; 9%). There was a significantly higher risk of being readmitted in males (Female odds ratio: 0.87; confidence interval [0.851-0.922), older patients (65-79: 32.3%; > 80: 37.1%), patients with three or more comorbidities (≥ 3: 32.9%), or in patients discharged to a skilled nursing facility/intermediate care facility/rehab (SNF/ICF/Rehab odds ratio: 1.55; confidence interval [0.234-0.262]). CONCLUSIONS: This study demonstrates a large proportion of patients are readmitted after sustaining a TBI. A significant number of patients are readmitted for subsequent injuries, circulatory issues, nervous system problems, and infections. Although readmissions cannot be completely avoided, defining at-risk populations is the first step of understanding how to reduce readmissions.

Higher Doses of Calcium Associated With Survival in Trauma Patients.

INTRODUCTION: Calcium is required for coagulation, cardiac output, and peripheral vascular resistance. Between 85% and 94% of trauma patients treated with massive blood transfusion develop hypocalcemia.1 The aim of this study is to evaluate the relationship between increased intravenous calcium administration during massive transfusion and improved survival of trauma patients. METHODS: We performed a retrospective analysis of trauma patients who received massive transfusion over a 2-y period. Doses of elemental calcium administered per unit of blood product transfused were calculated by calcium to blood product ratio (CBR). Chi-square test evaluated association between coagulopathy and 30-d mortality. Two-sample t-test evaluated association between CBR and coagulopathy. Bivariate regression analysis evaluated association between CBR and blood products transfused per patient. Multivariable logistic regression analysis, controlling for age, sex, coagulopathy, and Injury Severity Score evaluated the association between CBR and mortality. RESULTS: The study included 77 patients. Coagulopathy was associated with increased 30-d mortality (P < 0.05). Patients who survived had higher CBR than those who died (P < 0.05). CBR was associated with a significant reduction in total blood products transfused per patient (P < 0.05). CBR was not associated with coagulopathy (P = 0.24). Multivariable logistic regression analysis demonstrated that Injury Severity Score ≥16, coagulopathy and decreased CBR were significant predictors of mortality (P < 0.05). CBR above 50 mg was a predictor of survival (P < 0.05). CONCLUSIONS: Higher doses of calcium given per blood product transfused were associated with improved 30-d survival and decreased blood product transfusions.

Weight-Based Dosing for Venous Thromboembolism Prophylaxis in Spinal Trauma Patients Appears Safe.

INTRODUCTION: Venous thromboembolism (VTE) is a substantial cause of morbidity and mortality in trauma patients. VTE prophylaxis (VTEP) initiation is often delayed in certain patients due to the perceived risk of bleeding complications. Our VTEP guideline was changed from fixed-dosing to a weight-based dosing strategy using enoxaparin in June 2019. We investigated the rate of postoperative bleeding complications with a weight-based and a standard dosing protocol in traumatic spine injury patients requiring surgical stabilization. METHODS: A retrospective pre-post cohort study using an institutional trauma database was conducted, comparing bleeding complications between fixed and weight-based VTEP protocols. Patients undergoing surgical stabilization of a spine injury were included. The preintervention cohort received fixed-dose thromboprophylaxis (30 mg twice daily or 40 mg daily); the postcohort received weight-based thromboprophylaxis (0.5 mg/kg q12 h with anti-factor Xa monitoring). All patients received VTEP 24-48 h after surgery. International Classification of Diseases codes were used to identify bleeding complications. RESULTS: There were 68 patients in the pregroup and 68 in the postgroup with comparable demographics. Incidence of bleeding complications in the pre- and postgroups were 2.94% and 0% respectively. CONCLUSIONS: VTEP initiated 24-48 h after surgical stabilization of a spine fracture using a weight-based dosing strategy and has a similar rate of bleeding complications as a standard dose protocol. Our study is limited by the low overall incidence of bleeding complications and small sample size. These findings could be validated by a larger multicenter trial.

Closed Collaborative Surgical Intensive Care Unit Modeling and Its Association With Trauma Patient Outcomes.

INTRODUCTION: The optimization of intensive care unit (ICU) care impacts clinical outcomes and resource utilization. In 2017, our surgical ICU (SICU) adopted a "closed-collaborative" model. The aim of this study is to compare patient outcomes in the closed-collaborative model versus the previous open model in a cohort of trauma surgical patients admitted to our adult level 1 trauma center. METHODS: A retrospective review of trauma patients in the SICU from August 1, 2015 to July 31, 2019 was performed. Patients were divided into those admitted prior to August 1, 2017 (the "open" cohort) and those admitted after August 1, 2017 (the "closed-collaborative" cohort). Demographic variables and clinical outcomes were analyzed. Trauma severity was assessed using injury severity score (ISS). RESULTS: We identified 1669 patients (O: 895; C: 774). While no differences in demographics were observed, the closed-collaborative cohort had a higher overall ISS (O: 21.5 ± 12.14; C: 25.10 ± 2.72; P < 0.0001). There were no significant differences between the two cohorts in the incidence of strokes (O: 1.90%; C: 2.58%, P = 0.3435), pulmonary embolism (O: 0.78%; C: 0.65%; P = 0.7427), sepsis (O: 5.25%; C: 7.49%; P = 0.0599), median ICU charges (O: $7784.50; C: $8986.53; P = 0.5286), mortality (O: 11.40%; C: 13.18%; P = 0.2678), or ICU length of stay (LOS) (O: 4.85 ± 6.23; C: 4.37 ± 4.94; P = 0.0795). CONCLUSIONS: Patients in the closed-collaborative cohort had similar clinical outcomes despite having a sicker cohort of patients. We hypothesize that the closed-collaborative ICU model was able to maintain equivalent outcomes due to the dedicated multidisciplinary critical care team caring for these patients. Further research is warranted to determine the optimal model of ICU care for trauma patients.

Improved Confidence and Clinical Application: The Effects of a Longitudinal Suture Curriculum for Medical Students.

OBJECTIVE: The ability to competently suture is an expected skill for graduating medical students, but many graduates report feeling unprepared to perform this skill. This study aimed to improve student confidence and clinical readiness for third-year clerkships by implementing a novel, mandatory 7.5-hour longitudinal suturing skills curriculum across the first 3 years of medical school. METHODS: The required suturing skills curriculum was implemented for all medical students throughout the first 3 years of medical school at a large academic health center in the mid-South United States. Precurriculum (n = 167) and postcourse (n = 148) surveys were administered to first-year students in the first year of the curriculum (2017-2018), and a parallel follow-up survey was administered to this cohort in 2020 after students completed their clinical clerkship year (n = 82). Aggregate changes in students' survey responses were analyzed for proper instrument position, simple interrupted sutures, and instrument ties using independent groups Mann-Whitney U tests and Rosenthal correlation coefficients for effect sizes. RESULTS: Statistically significant improvement from pre to post was observed in student comfort in performing three basic skills: proper instrument position (P < 0.001), simple interrupted suture (P < 0.001), and instrument ties (P < 0.001). These pre-post gains were sustained at 2-year follow-up (P < 0.001). Also, the majority of students (66%) reported they were very or completely prepared to suture wounds during their clerkships. Most (83%) also reported they had successfully sutured patient wounds during third-year clerkships without needing significant direction or guidance. CONCLUSIONS: We found that a longitudinal suture curriculum with dedicated faculty involvement can improve student confidence in suturing and overall preparedness for third-year clerkships. Although the study is limited to ratings of student comfort and self-reported performance as well as some attrition of responses at postcourse survey and postclerkship survey, the findings highlight the importance of a focused curriculum dedicated to teaching basic suturing skills. Our findings also contribute to the limited body of work examining longitudinal surgical skills development for medical students.

Evaluating the Routine Use of Head Computed Tomography Angiography in Blunt Cerebrovascular Trauma.

BACKGROUND: The aim of this study was to evaluate a protocol change that mandated routine incorporation of head computed tomography angiography (CTA) for the work-up of suspected blunt cerebrovascular injury (BCVI) at an academic Level I trauma center. METHODS: The BCVI screening guidelines at our institution changed in 2018 to include the addition of a head CTA for all patients receiving a neck CTA as part of our BCVI screening guidelines. We performed a retrospective chart review of patients between 2018 and 2019 who were 18 years or older and met screening criteria for BCVI based on our institutional guidelines. The head CTAs of this cohort were assessed for findings that could potentially alter the course of the patients' treatment. RESULTS: A total of 319 patients fit this criterion and had a head CTA as part of their trauma workup. Findings that could potentially alter a patient's clinical course were identified in 6.6% (n = 21) of the head CTA's. These included decreased arterial perfusion (n = 9), active bleeds (n = 6), vessel occlusions (n = 1), aneurysms (n = 1), and vasospasms (n = 2). Of these 21 patients, 8 had clinically significant findings that affected their course of management (2.5% of total sample). They also had a higher mortality rate and ISS compared to the rest of the cohort. CONCLUSIONS: In patients with clinically suspected BCVI, the addition of head CTA to the existing BCVI screening guideline identified clinically significant vascular abnormalities that affected management in 2.5% of cases.

An Educational Module to Teach Interprofessional Learner Feedback Skills for Trauma Simulation Events.

BACKGROUND: Peer feedback, or feedback given by a learner to another learner, is an important active learning strategy. Hierarchy and stereotypes may affect interprofessional (IP) learner-to-learner feedback. The aim was to assess the efficacy of an educational module for IP learners in delivering effective feedback during trauma simulations. METHODS: Multiple simulation events designed to improve teamwork and leadership skills during trauma simulations included IP learners (residents and nurses). Participants completed a pre-course educational module on IP peer feedback. The Trauma Team Competence Assessment-24 tool structured feedback. Learners completed pre/post-assessments utilizing IP Collaborative Competencies Attainment Survey (ICCAS). RESULTS: Twenty-five learners participated in the trauma simulations (13 general surgery and 5 emergency residents, 3 medical students, 4 nurses). The majority of learners had either not received any previous training in how to effectively deliver peer feedback (40%) or had engaged in self-directed learning only (24%). Most learners (64%) had delivered peer feedback less than ten times. Learner knowledge and confidence in delivering feedback to fellow IP learners improved after simulations. All learners felt the feedback received was useful to their daily practice (68% agree, 32% strongly agree). All participants agreed that the simulation achieved each of the ICCAS competencies. CONCLUSIONS: Formal education on IP peer feedback is rare. This pilot work demonstrates educational modules with a foundation in validated tools can be effective in improving learner knowledge and confidence in the process. Engaging in IP peer feedback may also serve to flatten hierarchies that can challenge effective interprofessional teamwork.

ROTEM as a Predictor of Mortality in Patients With Severe Trauma.

BACKGROUND: Hemorrhage, especially when complicated by coagulopathy, is the most preventable cause of death in trauma patients. We hypothesized that assessing hemostatic function using rotational thromboelastometry (ROTEM) or conventional coagulation tests can predict the risk of mortality in patients with severe trauma indicated by an injury severity score greater than 15. METHODS: We retrospectively reviewed trauma patients with an injury severity score >15 who were admitted to the emergency department between November 2015 and August 2017 in a single level I trauma center. Patients with available ROTEM and conventional coagulation data (partial thromboplastin time [PTT], prothrombin time [PT], and international normalized ratio) were included in the study cohort. Logistic regression was performed to assess the relationship between coagulation status and mortality. RESULTS: The study cohort included 301 patients with an average age of 47 y, and 75% of the patients were males. Mortality was 23% (n = 68). Significant predictors of mortality included abnormal APTEM (thromboelastometry (TEM) assay in which fibrinolysis is inhibited by aprotinin (AP) in the reagent) parameters, specifically a low APTEM alpha angle, a high APTEM clot formation time, and a high APTEM clotting time. In addition, an abnormal international normalized ratio significantly predicted mortality, whereas abnormal PT and PTT did not. CONCLUSIONS: A low APTEM alpha angle, an elevated APTEM clot formation time, and a high APTEM clotting time significantly predicted mortality, whereas abnormal PT and PTT did not appear to be associated with increased mortality in this patient population. Viscoelastic testing such as ROTEM appears to have indications in the management and stabilization of trauma patients.

Is It Safe to Fly Patients with Penetrating Trauma in a Rural State?

BACKGROUND: There is limited data pertaining to the triage and transportation of patients with penetrating trauma in rural states. Large urban trauma centers have found rapid transport to be beneficial even when done by nonemergency medical staff. However, there is limited application to a rural state with only a single level 1 trauma center. MATERIALS AND METHODS: This a retrospective observational study of 854 trauma patients transported by helicopter emergency services between 2009 and 2015 to the state's only level 1 trauma center. RESULTS: After excluding patients with other injuries or lack of data, 854 patients underwent final analysis. Compared with penetrating trauma, blunt trauma had a significantly different chance of survival (92.0% versus 81.2%, P = 0.002) and a significantly different injury severity score (17 ± 12 versus 12 ± 9, P = 0.002). After controlling for blunt injuries, age, gender, injury severity score, tachycardia, tachypnea, hypotension, glasgow coma scale, and dispatch to hospital arrival time in multivariate analysis, blunt trauma had higher odds of survival than penetrating trauma (OR, 5.97; 95% CI, 2.52-14.12; P = <0.001 = 1). Gender, tachycardia, tachypnea, and dispatch to arrival time did not impact a patient's likelihood of survival. CONCLUSIONS: Penetrating trauma has a higher mortality when compared with blunt trauma in Helicopter Emergency Services transported patients in a rural state. Perhaps a new algorithm in the management of penetrating trauma would include hemorrhage control at a locoregional hospital before definitive care. Further study is required to understand the exact variables that lead to a higher mortality in penetrating trauma in a rural state.

Weight-Based Dosing for Low-Molecular-Weight Heparin (Enoxaparin) Administration to Achieve Optimal VTE Prophylaxis in Trauma Patients.

INTRODUCTION: Patients admitted after traumatic injuries are at high risk for developing venous thromboembolism (VTE). Low-molecular-weight heparin (LMWH) is commonly used to prevent VTE in this patient population; however, the optimal dosing strategy has yet to be determined. To address this question, a fixed-dosing strategy of LMWH was compared to a weight-based dosing strategy of LMWH for VTE prophylaxis. METHODS: A retrospective, pre-post implementation cohort study compared a fixed vs a weight-based dosing strategy of LMWH for VTE prophylaxis. Patients admitted to our level 1 trauma center were included if they had an estimated glomerular filtration rate >30 mL/min/1.73 m2, received at least 3 doses of LMWH, and had an appropriately drawn anti-Xa level on their initial dosing regimen. Patients in the pre-cohort received 30 mg LMWH subcutaneously twice daily as the initial dosing regimen. Patients in the post-cohort received .5 mg/kg (max 60 mg) LMWH subcutaneously every 12 h as the initial dosing regimen. A goal anti-Xa of .2-.4 IU/mL was targeted for prophylaxis. RESULTS: There were 817 patients in the fixed-dosing group (FDG) and 874 patients in the weight-based dosing group (WBDG). In the FDG, 42.8% of the patients achieved the goal initial anti-Xa level, with 54.1% and 3.1% reaching sub- and supratherapeutic doses, respectively. In the WBDG, 66.5% of patients reached goal initial anti-Xa levels, with 23.5% and 10.1% at sub- and supratherapeutic levels. The distribution of dose ranges was significantly different between the dosing strategies (P-value <.001). There was no difference in the number of patients who received blood products (39.1% vs 41.7%. P-value = .299). CONCLUSIONS: In our study, weight-based dosing of LMWH yielded a significantly higher proportion of patients who achieved goal prophylactic anti-Xa levels than fixed-dosing of LMWH. Larger-scale studies are needed to assess the risk of VTE events and bleeding with these dosing strategies.

Contemporary Rural Trauma Care.

The development of organized trauma systems has led to improved care for trauma patients, including those injured in rural areas. However, persistent disparities have led to increased awareness of the ongoing need for improvement. Our objective is to highlight distinctive aspects of rural trauma and propose opportunities for advancing rural trauma care.

Blue Rubber Bleb Nevus Syndrome: A Rare Case of Gastrointestinal Hemorrhage Necessitating Bowel Resection.

Blue Rubber Bleb Nevus Syndrome is a congenital rarity that manifests as vascular malformations throughout the body, including the gastrointestinal tract. With fewer than 300 cases reported, the etiology and clinical course is poorly understood; however, the literature suggests TEK mutations on chromosome 9 result in unregulated angiogenesis. We present the case of a young female treated for anemia of unknown etiology who presented in hemorrhagic shock due to gastrointestinal hemorrhage necessitating small bowel resection, with cutaneous, intestinal, hepatic, and lingual vascular malformations associated with a single somatic pathologic TEK mutation. Although uncommon, this case suggests that Blue Rubber Bleb Nevus Syndrome should be considered in the differential of a patient with persistent anemia and cutaneous lesions, carrying the potential for multiple gastrointestinal vascular malformations progressing to hemorrhage necessitating operative management. Additionally, a severe phenotype can occur without a double-hit TEK mutation.

Prophylactic Antibiotics in Patients with Traumatic Pneumocephalus or Cerebrospinal Fluid Leak.

INTRODUCTION: Pneumocephalus and cerebrospinal fluid (CSF) leaks are uncommon after trauma, but they expose the sterile CSF to environmental pathogens and create theoretical risk of central nervous system infection (CNSI). Prophylactic antibiotics are commonly given to these patients, but there is a paucity of evidence to guide this practice. We aim to quantify the incidences of these entities and analyze the efficacy of prophylactic antibiotics in preventing CNSIs. METHODS: A retrospective cohort study was conducted using our institutional trauma registry. All patients admitted from January 2014 to July 2020 with traumatic pneumocephalus (TP) or basilar skull fracture with CSF leak (BSF-CSF) were included. ICD-9 and ICD-10 codes were used to identify CNSIs. CNSI rates among defined prophylactic antibiotic regimens, no antibiotics, and other antibiotic regimens were evaluated. ANOVA was used to analyze differences between the groups. RESULTS: 365 patients met inclusion criteria: 360 with TP; 5 with BSF-CSF. 1.1% (4/365) of patients developed CNSI, all with isolated traumatic pneumocephalus. 1.4% of patients (1/72) without antibiotics; 1.2% (3/249) receiving IV antibiotics outside of a defined regimen; and 1.1% (1/88) on a designated prophylactic regimen developed CNSIs. ANOVA indicated the incidence of CNSI was not significantly different among patients who received antibiotics or not, regardless of the regimen (p-value 0.958). CONCLUSION: TP and BSF-CSF are rare diagnoses among trauma patients. The rate of CNSI is marginal and antibiotics do not appear to confer a protective advantage. A larger trial is needed to elucidate the true effect of antibiotics on preventing CNSIs in patients with these uncommon diagnoses.

Are Chest Radiographs or Ultrasound More Accurate in Predicting a Pneumothorax or Need for a Thoracostomy Tube in Trauma Patients?

BACKGROUND: Historically, chest radiographs (CXR) have been used to quickly diagnose pneumothorax (PTX) and hemothorax in trauma patients. Over the last 2 decades, chest ultrasound (CUS) as part of Extended Focused Assessment with Sonography in Trauma (eFAST) has also become accepted as a modality for the early diagnosis of PTX in trauma patients. METHODS: We queried our institution's trauma databases for all trauma team activations from 2021 for patients with eFAST results. Demographics, injury variables, and the following were collected: initial eFAST CUS, CXR, computed tomography (CT) scan, and thoracostomy tube procedure notes. We then compared PTX detection rates on initial CXR and CUS to those on thoracic CT scans. RESULTS: 580 patients were included in the analysis after excluding patients without a chest CT scan within 2 hours of arrival. Extended Focused Assessment with Sonography in Trauma was 68.4% sensitive and 87.5% specific for detecting a moderate-to-large PTX on chest CT, while CXR was 23.5% sensitive and 86.3% specific. Extended Focused Assessment with Sonography in Trauma was 69.8% sensitive for predicting the need for tube thoracostomy, while CXR was 40.0% sensitive. DISCUSSION: At our institution, eFAST CUS was superior to CXR for diagnosing the presence of a PTX and predicting the need for a thoracostomy tube. However, neither test is accurate enough to diagnose a PTX nor predict if the patient will require a thoracostomy tube. Based on the specificity of both tests, a negative CXR or eFAST means there is a high probability that the patient does not have a PTX and will not need a chest tube.

Geospatial Analysis of Prehospital Triage and Early Potential Preventable Traumatic Deaths.

Severely injured patients often depend on prompt prehospital triage for survival. This study aimed to examine the under-triage of preventable or potentially preventable traumatic deaths. A retrospective review of Harris County, TX, revealed 1848 deaths within 24 hours of injury, with 186 being preventable or potentially preventable (P/PP). The analysis evaluated the geospatial relationship between each death and the receiving hospital. Out of the 186 P/PP deaths, these were more commonly male, minority, and penetrating mechanisms when compared with NP deaths. Of the 186 PP/P, 97 patients were transported to hospital care, 35 (36%) were transported to Level III, IV, or non-designated hospitals. Geospatial analysis revealed an association between the location of initial injury and proximity to receiving Level III, IV, and non-designated centers. Geospatial analysis supports proximity to the nearest hospital as one of the primary reasons for under-triage.

Access to Immediately Available Balanced Blood Products in a Rural State's Trauma System.

INTRODUCTION: The Arkansas Trauma System was established by law more than a dozen years ago, and all participating trauma centers are required to maintain red blood cells. Since then, there has been a paradigm shift in resuscitating exsanguinating trauma patients. Damage Control Resuscitation with balanced blood products (or whole blood) and minimal crystalloid is now the standard of care. This project aimed to determine access to balanced blood products in our state's Trauma System (TS). METHODS: A survey of all trauma centers in the Arkansas TS was conducted, and geospatial analysis was performed. Immediately Available Balanced Blood (IABB) was defined as at least 2 units (U) of thawed plasma (TP) or never frozen plasma (NFP), 4 units of red blood cells (RBCs), 2 units of fresh frozen plasma (FFP), and 1 unit of platelets or 2 units of whole blood (WB). RESULTS: All 64 trauma centers in the state TS completed the survey. All level I, II, and III Trauma Centers (TCs) maintain RBC, plasma, and platelets, but only half of the level II and 16% of the level III TCs have thawed or never frozen plasma. A third of level IV TCs maintain only RBCs, while only 1 had platelets, and none had thawed plasma. 85% of people in our state are within 30 min of RBCs, almost two-thirds are within 30 min of plasma (TP, NFP, or FFP) and platelets, while only a third are within 30 min of IABB. More than 90% are within an hour of plasma and platelets, while only 60% are within that time from an IABB. The median drive times for Arkansas from RBC, plasma (TP, NFP, or FFP), platelets, and an immediately available and balanced blood bank are 19, 21, 32, and 59 minutes, respectively. A lack of thawed or non-frozen plasma and platelets are the most common limitations of IABB. One level III TC in the state maintains WB, which would alleviate the limited access to IABB. CONCLUSION: Only 16% of the trauma centers in Arkansas can provide IABB, and only 61% of the population can reach IABB within 60 minutes. Opportunities exist to reduce the time to balanced blood products by selectively distributing WB, TP, or NFP to hospitals in our state trauma system.

Increased Lengths of Stay, ICU, and Ventilator Days in Trauma Patients with Asymptomatic COVID-19 Infection.

BACKGROUND: The SARS-Cov-2 coronavirus has varying clinical effects-from asymptomatic patients to life-threatening illness and death. At the only Level 1 Trauma Center in a rural state, outcomes appeared worse in trauma patients who tested positive for COVID despite these patients presumably being asymptomatic or only mildly affected before their traumatic event. This study compares all trauma admissions that were COVID-positive to those who were not. METHODS: The institutional database was queried for all level 1 and 2 trauma activations from March 2020-July 2021. The analysis consisted of a multivariate regression between COVID-negative and the COVID-positive group controlling for age, injury severity score (ISS), and Glasgow Coma Score (GCS). Outcomes compared were hospital length-of-stay (LOS), ICU LOS, ventilator days, days to discharge to a facility, and in-hospital mortality. RESULTS: Hospital LOS was 2.7 days longer in the COVID-positive group (P < .0005). ICU LOS was 2.9 days longer for patients admitted to the ICU in the COVID positive-group (P = .017). Ventilator days were 4.7 days longer for patients requiring mechanical ventilation in the COVID-positive group (P = .002). Discharge to a post-acute facility required 6.1 more days in the COVID-positive group (P = .005). CONCLUSION: Trauma patients presenting positive for COVID-19 are presumed to be asymptomatic before their traumatic event. Despite this, the physiologic toll of trauma combined with the COVID infection causes significantly worse clinical outcomes, including increasing hospital days in this patient population, which continues to tax the already burdened healthcare system.

Percutaneous Cholecystostomy Tubes versus Medical Management for Acute Cholecystitis.

BACKGROUND: Cholecystitis is one of the most common infections treated surgically in the United States. Surgical risk is prohibitive in some patients, leading to alternative therapeutic strategies, including medical management (antibiotics) with or without percutaneous cholecystostomy tube (PCT) drainage. MATERIALS AND METHODS: Using the Healthcare Cost and Utilization Project (HCUP) National Readmission Database (NRD), we performed a retrospective review to compare medically managed patients with or without PCT placement by evaluating 60-day readmissions rates, health care costs, and hospital length of stay (LOS). Both study groups were matched using the Elixhauser comorbidity index, age, and sex. Univariate and multivariate statistical analyses were performed using STATA. RESULTS: 776,766 patients were included in the analysis. The population receiving PCT placement was on average 16 years older (69.9 vs 53.6 years; P < .01), less likely to be female (40.7% vs 59.3%; P < .01), and had almost twice as many comorbidities (3.36 vs 1.81; P < .01) compared to the population receiving medical management. After matching our data to account for these incongruities, PCT patients were still 10.4 times more likely to be readmitted, had a 11.6% increase in the cost of care, and a 37.6% increase in LOS compared to those managed medically. DISCUSSION: Percutaneous cholecystostomy tube placement for cholecystitis is associated with a higher readmission rate, increased charges, and increased LOS compared to antibiotic therapy alone, even after correcting for age, sex, and comorbidities.

An Analysis of Traumatic and Non-Traumatic Hemopericardium Using Autopsy Data From a County Medical Examiner.

The volume of hemopericardium requiring hemodynamic changes in the trauma patient is not well understood. We performed a study using autopsy data from trauma patients who died with hemopericardium (>20 mL). Of 1848 traumatic deaths, 54 had hemopericardium at autopsy. The median pericardial blood in this group was 150 mL, which is more than the previously assumed volume to be lethal in trauma patients. Therefore, it may be appropriate to redefine the estimated volume required to cause lethal hemopericardium in trauma patients.

An Evaluation of Pediatric Gastrocutaneous Fistula Closure Through the Punch Excision of Epithelized Tract Procedure.

BACKGROUND: Persistent gastrocutaneous fistulae frequently complicate gastrostomy tube placement. A minimally invasive technique for tract closure employing balloon catheter retraction and punch excision of the epithelized tract (PEET) was recently reported. We hypothesized the PEET technique of closure would lead to decreased complications without an increased incidence of recurrence. METHODS: We conducted a single-center retrospective cohort study evaluating children who underwent gastrocutaneous fistula (GCF) closure 1/1/2018-12/31/2021, comparing patients who underwent the PEET procedure to those repaired with layered closure. Procedure duration and outcomes were additionally compared to the 2018-2019 National Surgical Quality Improvement Program (NSQIP) Participant Use File (PUF) database. RESULTS: Sixty-two children underwent operative GCF closure, including 25 with PEET and 37 traditional layered closure. Procedural time was significantly decreased employing PEET (14 vs 26 minutes, P < .0001), less than half the national median by the NSQIP PUF database of 292 GCF closures (14 vs 34.5 minutes, P < .0001). Those repaired with the PEET method experienced no episodes of recurrence, surgical site infection, readmission, reoperation, or mortality within 30 days of the procedure. Conversely, in traditional closure, there was a 24.3% complication rate, including 7 surgical site infections, 1 readmission, and 2 unplanned reoperations. National procedural complication rate by NSQIP PUF was 5.5%, with a 4.8% rate of surgical site infection, .3% reoperation incidence, and .3% mortality. DISCUSSION: Our study suggests GCF closure employing the PEET procedure is a safe, more efficient method of tract closure than the traditional layered closure technique.
